BOLS'IER END MEMBER.

Specification of Letters Patent.

Patented Au 2st,

Application filed December 21, 1914. Serial No. 878397.

T 0 all whom it may concern:

Be it known that I, JOHN l/V. RANKIN, a citizen of the Dominion of Canada, and resident of the city of Montreal, in the Province of Quebec and-Dominion of Canada, have invented certain new and useful Improvements in Bolster End Members, of

Y which the following is a full, clear, and exact description. I

This invention relates to improvements in bolster end members, and the object is to provide an end member having a wearing plate of harder material inserted therein where the end member bears in the truck side frame.

A further object is to provide a bolster end member and wearing plate of simplified construction, so arranged that the wearing plate may be inserted with a minimum expenditure of time, and will be very securely held.

The device consists essentially of an end member of any suitable type having a shallow pocket formed therein at the point of engagement with the truck frame. This pocket opens at the inner end of the memher and connects at the outer end with a small passage formed through the guide flange. The wear plate, which is provided with a suitable tongue, is inserted in the pocket from the inner end, the tongue passing through the flange passage and being clenched over the flange to prevent the plate backing out.

In the drawings which illustrate the inention:l igurc 1 is a side elevation of a bolster end member with the improved wear plate in position. Fig. 2 is a half plan view of the end member. Fig. 3 is a hali' cross section on the line 3---3, Fig. 1.

Referring more particularly to the drawings, 5 designates a bolster end member of any suitable form having side plates 6 provided adjacent the outer end with a guide flange 7 and adjacent the inner end with guide lugs 55, said flange and lugs embracing between them the truck frame. The side plate is provided with a shallow pocket 9 c-fending from. the flange '4' towar t re inner end of the plate. This pocket is bounded at the upper and lower edges of the plate by low ribs 10, which may be so low that the wear plate will pro]ect above them. The adjacent portions of the lugs 8 are undercut, as shown at 11, in line with the adjacent edges of the ribs 10, thus forming straight upper and lower edges for the pocket. One or more slots 12 are formed through the flange 7 in the plane of the pocket 9.

The wear plate 13 is a rectangular sheet of metal, preferably slightly thicker than the ribs 10 and provided with a tongue ll adapted to pass through the slot 12, and be clenched over on theflange 7, as clearly shown in Figs. 1 and 2. The plate 13 is thus held against backing out of the pocket and cannot move forwardly on account of the flange 7 which it abuts. Vertical movement is checked by the ribslO and movement away from the side plate is prevented by the overlapping portions of the lugs S and the en agement of the tongue in the slot.

The operation of inserting a wear plate is extremely simple. The plate is slipped tongue end first under the overhanging lugs 8 and advanced until the tongue passes through the slot 12 and the end of the plate abuts the flange 7. The tongue is then I clenched over and the operation is complete.

From the foregoing description, it will be obvious that the cost of making and insertinga wearing plate is reduced to a minimum. Worn plates may be very quickly and easily exchanged for fresh ones. The-casting of the end member as arranged for the reception of this plate presents no complications,

and the additional cost is practically negligible. The lugs 8 may if desired be continued in a vertical direction so as to meet and form a continuous bearing flange, but it is doubtful if such structure would have any advantage.

Having thus described my invention, what I claim is:

1. A, bolster end member having pockets in the sides thereof opening toward the inner end of the member and slotted guide flanges adjacent the outer ends of said memher, and wearing plates inserted in said pockets projecting through the flange pas sages and clenched over the flanges.

2. A device of the character described, comprising a bolster end member having sid plates provided at their outer ends with slotted flanges, undercut lugs at the inner ends of said side-plates, ribs on the side plates between the lugs and flanges, and

Wearing plates passing'under the lugs and between the ribs and projecting through the flange slots.

3. A device of the character described, comprising a bolster end member, Wearing plates of harder material on the sides there of, guide flanges on the sides of said member forming abutments for said plates, top and bottom plate holdin ribs on the memher, top and'bottom gui e lugs overlapping and holding said plate, and tongues on the plate passing through and clenched over the guide flanges.

4:. A device of the character described, comprising the combination with a bolster end member, of Wear plates of harder material, abutments for said plates formed on the sides of the member and holding the plates against vertical movement and horizontal movement in one direction, tongues on said plates passing through and folded over the member and holding the plates against movement in a second horizontal direction, and lugs on the member overlapping said plates and cooperating'with the tongues thereof to hold the plates against movement away from the member.

In Witness whereof, I havehereunto set my hand, in the presence of two Witnesses JOHN W. RANKIN. Witnesses S. ;R. W. ALLEN, G. M. 'MORELAND.
